Fish, Crab and Macroinvertebrate Guides
The Hudson River is full of a wide variety of fish and macroinvertebrates. Of course certain fish and certain macros will prefer different types of environments such as:
- Some species prefer freshwater, some are more marine species hopin for salty water and some look for a blend of fresh and salt called brackish water
- Some species like underwater plant beds called 'submerged aquatic vegetation’, some open water
- Some species prefer a soft muddy bototm, others a sandy bottom and still other like a rocky, cobbly bottom
- Some species look for a deep, cool, fast-flowing water while others look for shallow, warmer slow moving sections of water
Some species prefer different environments at different times of the year, or in different stages of their lives. Identifying the different type of fish (diversity) and the number of each (density) in each area and catch (seine, minnow cage, rod and reel) provides a picture of the marine life inhabits each area of the river.
